Find materials for this course in the pages linked along the left. These problems are called boundary-value problems. The finite difference method is used to solve ordinary differential equations that have conditions imposed on the boundary rather than at the initial point. NPTEL provides E-learning through online Web and Video courses various streams. Higher order equations (c)De nition, Cauchy problem, existence and uniqueness; Linear equations of order 2 (2.2) This is a system of diﬀerential equations of order 12 (we have a diﬀerential equation of order 2 for each of the 3 components of the two vectors ρ1 and ρ2, the equations being coupled to each other).
